Abstract

For moving an element (6) in an axial direction relative to an object (8), a plurality of screw members (9) are screwable in the element (6) and are arranged around an axis (A) so as to be spaced from one another, each of the screw members (9) has a first end adapted to interact with the object (6) and an opposite second end, and a drive unit includes an action drive and a reaction drive arranged coaxially to the axis (A) and with one another and turnable in opposite directions, one (4, 5) of the drives engages an outer circumference of the screw members (9) while the other (2, 3) of the drives engages an inner circumference of the screw members (9) so that when the power tool is activated the drives (2, 3; 4, 5) are turned in opposite directions and turn the screw members (9) in one and the same direction to thereby move the element (6) in the axial direction. <IMAGE>
